Versuchsvorschrift

A solution of 6,7-dimethoxy-1-(3-methoxy-benzoyl)-isoquinoline-4-carboxylic acid (30mg, 81.7 mmol), ammonium chloride (43.5 mg. 0.817 mM) and triethylamine (0.115 mL, 0.817 mM) in 2 mL of dimethylformamide was stirred with O-benzotriazol-1-yl-N,N,N,N-tetramethyluronium hexafluorophosphate (61.9 mg. 0.163 mM) at room temperature for 20 hours. Poured into 20 mL of water and 20 mL of ethyl acetate, extracted ethyl acetate layer with saturated sodium bicarbonate, dried ethyl acetate solution. over anhydrous magnesium sulfate and evaporated to give 5.4 mg of an off-white solid pure product: APCI-MS m/e calcd for C20H18N2O6 (M+H.) 367.4, found 367; H NMR (300 MHz) compatible.
